V MACHINERY FOR MANUFACTURING HORSESHOES.

SPECIFICATION forming part Of Letters Patent N0. 666,075, dated January15, 1901.

Application filed October 16, 1900. Serial lie-33,238. KNo model.)

To all whom it may concern:

Be it known that I, JAMES VERNON, upholsterer, of Newton-Stewart,Scotland, have invented certain new and useful Improvements in Machineryfor Manufacturing Horseshoes, of which the following is a specification.

The present invention has reference to machinery for use in themanufacture of cast steel or iron horseshoes, and has for its object toinsure a better product than has previously been regularly obtained.

Hitherto the chill or metal-mold has been so constructed that there wassome difficulty.

in disengaging the casting therefrom with sufficient rapidity to avoiddefects arising from shrinkage while in the mold.

The chills usually employed hithertohave comprised a fixed back part,with the recess for the casting therein, and a movable cover or front,the nail-hole cores being inserted at the proper inclination into themold through the back part.

According to the present invention the back is movable as well as thefront, and there is a center part which retains the casting and supportsit externallywhen the other portions of the mold are withdrawn,which isdone immediately the casting is sufficiently set, so that the shrinkagecannot cause damage therein.

In the accompanying drawings I have shown a horseshoe-casting machineembodying my improvements.

Figure 1 is a plan View, and Fig. 2 isa side elevation, of the mold in aclosed condition. Fig. 3 is a sectional plan of the mold closed on theline 3 of Fig. 2, and Fig. 4 is a similar view on the same line open.Fig. 5 is a front view of the middle plate of the mold, and Fig. 6 is afront View of the front part or cover.

A is the center or fixed portion of the mold, mounted vertically on asolid bracket or framing. (Not shown in the drawings.)

B is the cover, sliding on the rods act, carried horizontally by theplate A.

O is the movable back plate, having an independent sliding movement onthe horizontal rods 0 0, carried by the back of the center plate A.

The mold is formed in the portions or plates A and O, the formerproviding the external circumference and the latter the innercircumference and back. The coverB completes the chill by inclosing thefront. The mouth or gate X of the runner-hole w is furnished by anupward extension of the parts B and C. The nail-h ole cores d,of whichthere are eight, (see Fig. 5,) project through the back plate C ininclined directions. (See Figs. 3 and 4.) These cores are carried onstems d3, jointed to a frame D, which frame is capable of slidingbackward and forward on rods 6 e, fixed in the back of the plate 0.

The fram D consists of two plates d (1 braced together face to face, ashort distance apart. The former plate is pierced to permit the freepassage of the stems d of the cores d. The joint connection of thecorestems to the frame is efiected by means of loose socketpieces (1*engaging with balls 01 on the core-stem ends, Figs. 3 and 4. The stemscan rock freely in the sockets, and the latter themselves can move toand fro between the plates as occasion demands, the socket-pieces (1*being simply placed between the faces of the plates d d which, as abovestated, are braced or tied together face to face, and the socket-piecesare held in position by the balls (1 while free to slide on the faces ofthe plates d d as the core-stems rock. The extreme positions of thesesocketpieces in their movement between the plates (1 d are shown inFigs. 3 and 4.

The movement of the cover Bis effected by the double-handled lever b,which is pivoted centrally thereto. (See Fig. 6.) By means of this leverthe cover B may be drawn out into the dotted position of Fig. 2 orthrust home into the drawn position, Where it may be. locked by engagingthe lever with the studs co co, projecting through the cover B from theplate A. (See Fig. 6.) The back part .0 is normally pressed up againstthe fixed plate A by the springs c, which embrace the rods 0 and bearagainst the fixed crosshead 0 carried by the rods 0 and the bosses c onthe back of the plate 0. ,To Withdraw the plate 0, a cam device isemployed operated by a handle 1. The cam device comprises a verticalspindle F, passing through the fixed cross-head c and carryingeccentri'cally-mounted bowls f. These bowls engage with portions of arectangular frame f attached to the plate 0, and thereby withsimilar tothat just described with regard to theplateO.eearepressure-springstending to advance the cores in a forwarddirection. G is a double-ended chisel for severing the runner from thecasting. This chisel G is operated by a handle 3 by means of a camdevice having spindle F and eccentricallymounted bowls f like thosealready described.

To make a casting, the parts of the mold are put together, as in Figs. 1and 2, and locked. The metal is then run in, the nailcores operated, andthe back plate 0 immediately withdrawn. This leaves the castingsupported externally in the plate A, so that any shrinkage which takesplace incooling does not tend to bind the shoe in the mold and cause itto crack or split. The castingis prevented from following the back 0,when the latter is withdrawn, by the beveled form of the recess in theplate A, which is best seen at Figs. 3 and 4. After the back 0 has beenwithdrawn the cover B can be drawn back and the casting removed at convenience. The

retirement of the nail-hole cores will immediately precede thewithdrawal of the back 0, so that the latter will be thereby freed tomake a more rapid release of the still-heated able ladle by which themolten metal is sup- I plied. A mechanical conveyer for the ladle ispreferably furnished.

I claim l. A mold or chill for casting horseshoes, comprising threevertical portions, one of .which is a fixed middle portion and theothers movable toward and from the faces of the fixed middle portion toclose and open the mold, and a set of inclined movable cores projectingthrough one of the portions into the mold'for making nail-holes in thecasting, substantially as set forth. 7

2. In a mold for casting horseshoes, the combination with a fixed middlepart of the mold, of back and front parts of the mold movable toward'andfrom said middle part to close and open the mold; removable moldportions or linings carried by said back and front parts, and inclinednail-hole cores projecting through the back part into the interior ofthe mold, substantially as set forth.

3. In a mold for casting liorseshoes, the combination with a fixedmiddle partforming the exterior circumference of the mold, of a backpart forming the inner circumference and back of the mold, and a coverinclosing the front of the mold, said back part and cover being movabletoward and from the faces of the fixed middle part to close and open themold, and inclined nail-hole cores projecting through the back part intothe interior of the mold, substantially as set forth.

4:. "In a mold for casting horseshoes having two movable and one fixedportion, a set of inclined nail-hole cores, an operating device foradvancing and withdrawing said cores,

balland -socket attachment for connecting the cores to the operatingdevice whereby movement in a lateral and vertical direction is freelypermitted substantially as set forth.
